TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY KILLAM, of New Haven, iii the county of New Haven, and State of Connecticut, have invented new Improvement in Machine for Compressing,Carriage-Wheels; and I do hereby declare the fol/lowing., when taken inl connection with the accompanying drawings and the letters of-ref'erence marked thereon, to be a. full, clear, and exact .description of the saine, and which said drawings constitute part of this speciication, and represent, in A Figure 1, a top view, and in Figure 2, a vertical central section on line :z: x.

This invention relates to an improvement in the manufacture of carriage-wheels, and consists in an appa ratus for compressing the felloc on to the spokes preparatory to receiving the tire, its object being to bring the felloe to a solid bearing upon all the spokes, and to compress the whole wheel tightly together in all its parts.

Various devices have been used to accomplish this object,rthe most successful being that of a screw arranged to compress against the felloe at each spoke like an ordinary vise or clamp, as see the patent to George Cook,

July 21,1863.

Torenable others to construct and use my improvement, I will proceed to describe' the same as illustrated in the accompanying drawings. i

A is a plate or frame, as the case may be, constructed with radial grooves or guides to receive jaws B B, more or-less in number, which should correspond to the number of spokes. Upon the underside of the said jaws are formed teeth, as seen in fig. 2, and beneath the frame or plate which supports the jaws-is arranged another plate, C, having a spiral groove or thread formed thereon, corresponding tothe teeth upon the under side of the I by Letters Patent, `isi-- jaws;l the said plate C being xed to any convenient framework D, or other arrangement that will hold the said plate rm and strong in any fixed position, while the plate or frame A is constructed and arranged so as to turn freely and centrally upon the plate C. By the turning of the frame or plate A upon the plate C, the

jaws B are turned with the plate` A, and the teeth on the said jaws, followingin the spiral groove upon the fixed plate (LareforcedY from or drawn toward the centre, according to the direction in which they are turned, and thesaid plate or 4'frame A andjaws B are so'turned in any cenvenientmanner.

In g; 1 .a wheel is represented in -red as placed upon the machine preparatory to compressing the jaws having-first lee'n extended so asto permit the wheel to lie within their g'lrasp, and when so placed turn the plate A in the direction to draw the jaws firmly against the periphery of the'wheel. If then the felloebe too long, saw the joints in the usual manner, and again turn` up the jaws until lall parts of the wheel are firmly compressed together. By such compression only can a durable wheel be produced, and as such compression is necessary, it is desirable thatit should be equal at all points, and this can only be insured by jaws which move simultaneously; hence one great advantage which my invention has over other devices for this purpose. Another greatadvan tage is the saving of time'in so simultaneously moving all the jaws.

Having therefore thus fully described my invention, what I claim as new and useful, and desire tos'ecnre The combination and arrangement of the jaws B, and their guides or plates A, with the .plate C, when constructed so as to operate,substantially infthe manner heroin set forth.

HENRY KILLAM.
